G
direct sunlight.
G
nearby heat sources that may affect performance of the unit.
G
areas where leakage of flammable gas may be expected.
G
places where large amounts of oil mist exist.
DO:
G
select an appropriate position from which every corner of
the room can be uniformly cooled. (High on a wall is best.)
G
select a location that will hold the weight of the unit.
G
select a location where tubing and drain hose have the
shortest run to the outside. (Fig. 1)
G
allow room for operation and maintenance as well as unre-
stricted air flow around the unit. (Fig. 2)
G
install the unit within the maximum elevation difference (H)
above or below the outdoor unit and within a total tubing length

To prevent abnormal heat genera-
tion and the possibility of fire, do
not place obstacles, enclosures
and grilles in front of or surround-
ing the air conditioner in a way
that may block air flow.

If total tubing length becomes 25 to 50 ft. (Max.) or 25 to 65 ft. (Max.), charge additional refrigerant (R410A) by 0.16 oz./ft.
No additional charge of compressor oil is necessary. For more detailed charging information, refer to the Technical & Service Manual.
